Sunday houses were small second dwellings maintained near a church as a weekend place of residence. They became popular in the late 1800s among farmers and ranchers who lived in areas too remote to permit commuting to services. The families owning such houses normally left their farms and ranches Saturday morning, journeyed to town, took care of shopping and business, attended an evening dance or party, and spent the night in the Sunday house. On Sunday they attended church in the morning and either returned home in the afternoon or attended Sunday school in the afternoon, and then spent a second night in town. Sunday houses were also used when a member of the family needed to stay in town to conduct business or receive medical attention. Some of them had 1½ stories, with a gabled roof to form an attic, usually reached from an outside stairway, that served as the children's sleeping quarters.
The Schwarz "Sunday house" is on the grounds of the Sunday House Inn. It was built in the style of a Sunday house but not actually used as a traditional Sunday house. By 1900 William Schwarz and his family were living in this rock house at 911 S. Main Street, Boerne. It is said to have been built by him with the help of relatives and friends. There were three rooms on the bottom floor, bedroom, kitchen and dining room. The attic was finished later, with an outside stairway. Well-drilling was his listed occupation (1900 census) though he was much sought-after as a builder and rock mason. Schwarz was elected Marshall of the City of Boerne in 1914.
Unless there is something going on in the Main Plaza, the Boerne Hauptstrasse is really quiet in the evening. Most of the shops open at 9 AM and close at 5 PM, but a few stay open until 6 PM. Mague's Cafe opens for breakfast at 7 AM. The Bear Moon Bakery and Cafe opens at 6 AM but the breakfast buffet does not start until 8 AM. You may as well sleep late.
